What you're doing right now is proof of quantum theory
Will we ever understand it? Quantum physics has changed human society in remarkable ways. It is all around us, integrated into the digital technology of circuit chips and even in the light-emitting diodes, which are helping reduce our carbon footprint. This interplay between pure theory and its outcomes in the everyday world is a continuing feature as the study of quantum physics develops. Sidney Perkowitz, a professor of Physics Emeritus at Emory University, discusses how this realm of physics is interwoven in technology's past, present, and future.
